Memory is inherently unstable. Neurobiology has shown us that every time we recall an event, we pull it from storage, view it, and then rewrite it back to storage. This process, called reconsolidation, means that our memories are subtly rewritten by our present emotional state.
Your memory is not a video camera; it is a collaborative storyteller, constantly updating the narrative to make sense of who you are right now. We are the authors of our own pasts, whether we realize it or not.
